A Santa Ana 23-year-old has been arrested for the murder of a man who was whacked on the back of his head with a skateboard while he was sitting on a bench in San Francisco's Golden Gate Park last Friday evening.

Marcus Herrera, who is also accused of stealing the wallet of Robert Musial, 55, was arrested while riding a Muni bus Sunday morning.Witnesses say Musial struggled to breathe and called for help after the attack and robbery, but he was unconscious around 7:30 p.m. Friday when police and paramedics arrived. He later died, and an autopsy concluded blunt-force trauma to the head was the cause.

An investigation around Sharon Art studio, near where Musial died, led to Herrera being considered a suspect. He was booked into the San
Francisco County Jail on suspicion of murder, robbery and assault with a
deadly weapon

Erin Sherbert blogs for SF Weekly that police are seeking witnesses to the violent mugging.

I am the public defender representing Marcus Herrera, who was born & raised in Northern California. I am very interested in talking with any witnesses to this incident. Eyewitnesses, Please contact me at 415.553.9300. Please do not respond by posting to this site. This article is grossly inaccurate on several points: from Santa Ana, skateboard to back of head, sitting on park bench, died of blunt force trauma, arrested on bus. It is a dark day for journalistic integrity. Additionally, johnrose7588 comment should be pulled due to its ignorant and racist content.

Typical dumb ass mexican. He must be from san tana. Not santa ana. Instead of jail, send that wet back back to mexico. Or better yet send him to guatamala where gustabo arliano was from. I here they dont raise murderers there just idiosos
